摘要： A vacuum cleaner which can alternately be used as a wet vacuum or a dry dust-free vacuum includes a suction head adapted to engage a surface to be vacuumed and a vacuum chamber which includes an inlet and outlet adapted to hold a quantity of liquid and solid material and liquid and other material entering the chamber through the inlet is prevented from entering the outlet. A partial vacuum is created in the chamber and a hose connecting the cleaning head and inlet creates suction in the head and transports material vacuumed from the surface to the chamber. A liquid nozzle with an outlet can be hooked up to spray liquid on the surface to be vacuumed near the suction head and liquid under pressure is supplied to the nozzle through a conduit. The liquid conduit can be connected to supply liquid to the nozzle so that the vacuum cleaner can be used to shampoo a surface or to a position where liquid is supplied to the interior of the hose so that material vacuumed from a surface will be combined with water before entering the chamber for dust-free operation.
